This was actually a really fun little project. It reminded me a lot of something I might've played on a 286 in the 90's. Also, that music is so... so perfectly nostalgic, bringing me back to the demo scene and some of the BBS's I used to haunt.
The mechanics are a little hard to parse at first, and the player could really use some iframes or enemy pauses after they're attacked. I got stunlocked a couple times by groups of the little slime dudes. Still, a very enjoyable experience, thanks for sharing this!
